We talk to a returning guest and friend of the show, science fiction author Edward M. Lerner, about his latest book 'On The Shoals of Space-Time', on the topic of First Contact. Ed is a fount of scientific insight and information on space science and the possibilities for extraterrestrial encounters, having written 25 books – 5 of them with the legendary author Larry Niven, of Ringworld fame – many of which explore themes First Contact with extraterrestrials, as well as future scientific advancement that would be necessary for interstellar travel. In this interview we discuss a number of his books, we talk about fusion and anti-matter, electromagnetic bottles, the Albercurrie drive for warping space-time to get around the speed limit of light, and neutrino communications. We also discuss the Prime Directive, the Drake equation, the Fermi Paradox, scientific revolutions and evolutions, stealth technologies, and alien monitoring stations keeping an eye on Earth in the Kuiper belt and the Oort cloud. That’s quite a lot! So if you like to dig deeper into the real science and big ideas in your science fiction, this conversation is a veritable treasury of insights and learning that will help you get more out of the science fiction you read and watch.

In this episode we talk to Mark Milne as a follow-up on our interviews with science fiction author Kim Stanley Robinson and glaciologist Heidi Sevestre in episodes 21 and 22, on the topic of Geoengineering as portrayed in Kim Stanley Robinson’s book 'The Ministry for the Future'. Mark speaks about a number of strategies for mitigating climate change by cooling the planet through increasing its albedo, or reflectivity. The overarching strategy that we discuss is Solar Radiation Management (SRM), and we tackle a number of different possibilities under this umbrella: stratospheric aerosol injection (SAI), marine cloud brightening, high albedo crops, reforestation, white paint, terrestrial mirrors and the Goliath that everyone likes to slay - space mirrors. Mark makes the case that terrestrial mirrors are our best hope for immediate implementation, with little or no dangerous side effects, especially in the context of canopies over agricultural land which can be created with current materials from landfill; if 10% of all agricultural land were covered with these semi-transparent mirrors it would provide enough global reflectivity to adequately offset our warming trend and avoid climate disaster. Marty proposes a sci-fi idea about adding engineered enzymes to create the materials we need, and Mark claims that if we don’t solve the climate crisis within a few decades it won’t be the heat that kills us, it’ll be people – due to the degradation of our social and economic systems. We also talk about governance and consent, what motivates scientists and determines the science we pursue, termination shock, carbon sequestration, engineering efficiency and economic policy initiatives related to modern monetary theory.

We continue the conversation between science fiction author Peter Watts and scientist Justin Gregg, and now they get down to the tricky business of discussing the nature of consciousness. We discuss Peter's premise of 'Blindsight – that consciousness is an illusory, unnecessary and possibly parasitic phenomenon that will get us all killed when we encounter more efficient, unconscious extra-terrestrial intelligence. Then very quickly agree that nobody knows what the hell they’re talking about when they try to understand consciousness: the pan-psychics may even be right that it’s a fundamental property of matter like mass, spin and charge. We discuss examples of unconscious but intelligent behaviour like sleepwalking killers and painters, we talk about acid trips, and the possible evolutionary advantages of consciousness in connection to memory. Peter suggests humans may not actually possess general intelligence and that we may be even dumber than large language models and the current incarnation of AI (as evidenced by flat earthers, anti-vaxxers and religious fundamentalists). And Justin promises to jello-wrestle an AI next time we get together!
